Summerville tells The Decatur Daily (http://bit.ly/1416Bez ) authorities are looking at ways to do things better in case of a repeat. He says possibilities include using billboard or twitter to inform motorists of blocked roads.

Hundreds of drivers had to spend the night on I-65 north of Cullman last Thursday after snow resulted in accidents and slippery conditions that brought traffic to a halt.

Some people complained that officials mishandled the situation.

Summerville says roads all over the area iced over, leading to the snarl.
